WAITING FOREVER FOR MY NEW LINE TO BE INSTALLED.

I used to a customer of Supersonic. Then went to Home-Connect. I moved recently, and thought let's try Supersonic again. Placed the order 1 Aug. Till today, I have been the one phoning them, to check up on my order. The ISP, who they appointed, has not even made an attempt to contact me, for Installation! I am fed-up with this poor service. Calls get cut off, nobody can tell me when this line will be installed. I am at work, not at home, so need to book off time from work, to be there, when they decide to Install. OpenServe, is the ISP.
